Wendy Koenig, North Central College associate professor of art, presented a paper, titled “New Approaches to Oral Testimony,” as part of the panel The Practice and Politics of Commemoration at the 11th Biennial International Holocaust Studies Conference at Middle Tennessee State University on Oct. 17. Her research into the use of audio and video testimony in Holocaust museums is an outgrowth of earlier work on acoustic design and the use of sound in Holocaust and other atrocity museum exhibits.
